Implement QUERY Method

[hawkinsw]

What's missing?

I am a huge fan of Rocket and thought that I could add support for the nearly-standardized QUERY method (https://www.ietf.org/archive/id/draft-ietf-httpbis-safe-method-w-body-05.html). I have a WIP PR that I will post to go along with this Feature Request. I have done my absolute best to make sure that I have followed all the proper steps.

Ideal Solution

I believe that the ideal solution is to simply add QUERY in the appropriate spot in the call(s) to the define_methods macro. Because QUERY is not yet an RFC, there will be a few changes to the define_methods macro so that the documentation is generated correctly.

Why can't this be implemented outside of Rocket?

Are there workarounds usable today?

Additional Context

Again, thank you for all the work that you are doing on Rocket. I understand that the PR that I will post does not have tests and that is absolutely a requirement. However, I wanted to post early/often to see whether support for QUERY is something that you would consider. If it is, then I will absolutely add all the tests necessary and clean up anything else that I have done incorrectly.

System Checks

• I do not believe that this feature can or should be implemented outside of Rocket.
• I was unable to find a previous request for this feature.
